LSU won 38-22 at home against the FCS opponent Saturday night and is ranked No. 4 in the new media poll.

Oregon remained No. 2 and Florida State moved past LSU to No. 3.

After beating Stanford on Thursday, Washington moved into the rankings at No. 23. No. 24 Northwestern is ranked for the first time this season.

David Ash threw three touchdown passes to Jaxon Shipley and Joe Bergeron scored on a 2-yard run with 29 seconds left to lift Texas to a 41-36 win over Oklahoma State. Ash directed the Longhorns (4-0, 1-0 Big 12) on a 75-yard scoring drive after the Cowboys (2-2, 0-1) had taken the lead on Quinn Sharp's 23-yard field goal with 2:34 to play.

Casey Pachall threw two touchdown passes, Jason Verrett had two interceptions and TCU extended its FBS-best winning streak to 12 games with a win over SMU.
